+USB HID Keyboard Device
+
+This example application turns the evaluation board into a USB keyboard
+supporting the Human Interface Device class. The color LCD display shows a
+virtual keyboard and taps on the touchscreen will send appropriate key
+usage codes back to the USB host. Modifier keys (Shift, Ctrl and Alt) are
+``sticky'' and tapping them toggles their state. The board status LED is
+used to indicate the current Caps Lock state and is updated in response to
+pressing the ``Caps'' key on the virtual keyboard or any other keyboard
+attached to the same USB host system.
+
+The device implemented by this application also supports USB remote wakeup
+allowing it to request the host to reactivate a suspended bus. If the bus
+is suspended (as indicated on the application display), touching the
+display will request a remote wakeup assuming the host has not
+specifically disabled such requests.

+//! <h1>USB HID Keyboard Device (usb_dev_keyboard)</h1>
+//!
+//! This example application turns the evaluation board into a USB keyboard
+//! supporting the Human Interface Device class. The color LCD display shows a
+//! virtual keyboard and taps on the touchscreen will send appropriate key
+//! usage codes back to the USB host. Modifier keys (Shift, Ctrl and Alt) are
+//! ``sticky'' and tapping them toggles their state. The board status LED is
+//! used to indicate the current Caps Lock state and is updated in response to
+//! pressing the ``Caps'' key on the virtual keyboard or any other keyboard
+//! attached to the same USB host system.
+//!
+//! The device implemented by this application also supports USB remote wakeup
+//! allowing it to request the host to reactivate a suspended bus. If the bus
+//! is suspended (as indicated on the application display), touching the
+//! display will request a remote wakeup assuming the host has not
+//! specifically disabled such requests.

+// Notes about the virtual keyboard definition
+//
+// The virtual keyboard is defined in terms of rows of keys. Each row of
+// keys may be either a normal alphanumeric row in which all keys are the
+// same size and handled in exactly the say way, or a row of "special keys"
+// which may have different widths and which have a handler function defined
+// for each key. In the definition used here, g_psKeyboard[] contains 6 rows
+// and defines the keyboard at the top level.
+//
+// The keyboard can be in 1 of 4 states defined by the current shift and
+// caps lock state. For alphanumeric rows, the row definition (tAlphaKeys)
+// contain strings representing the key cap characters for each of the keys
+// in each of the four states. Function DrawVirtualKeyboard uses these
+// strings and the current state to display the correct key caps.
